Pebblo Configuration File

Introduction

This configuration file specifies settings for various components of the Pebblo.

Configuration Details

Server

• port: Specifies the port number on which the Pebblo server listens for incoming connections.
• host: Specifies the host address on which the Pebblo server to run.

Notes:

1. By default Pebblo Server runs at localhost:8000. When we change values of port and/or host , the Pebblo Safe DataLoader env variable PEBBLO_CLASSIFIER_URL needs to set to the correct URL.
2. By default Pebblo UI runs at localhost:8000/pebblo. When we change values of port and/or host, the Pebblo UI would be running on the respective host:port/pebblo.

Logging

• level: Sets the logging level. Possible values are 'info', 'debug', 'error', 'warning', and 'critical'. Default value is info.
• file: Sets the log file path. Default value is /tmp/logs/pebblo.log.
• maxFileSize: Sets the maximum size of the log file. Default value is 8306688 bytes (8 MB).
• backupCount: Sets the number of backup files to keep. Default value is 3.

Reports

• format: Specifies the format of generated reports. Available options include 'pdf'.

• renderer: Specifies the rendering engine for generating reports. Options include 'weasyprint', 'xhtml2pdf'.

  Note
  Note: Using xhtml2pdf gives a report with basic UI elements, but WeasyPrint renderer creates a sleeker, better-aligned interface for your PDFs. See image below. If you put renderer as weasyprint, then you need to install Pango. Follow these instructions for the same.

  

• cacheDir: Sets the directory where pebblo stores metadata, generated reports, and other temporary files. Default value is ~/.pebblo.

• outputDir: Deprecated. Use cacheDir instead.

Classifier

• mode: Specifies mode for classify API. Possible values are all, entity or topic. Default value is all. When its value is all, both entities and topics will get classified, if value is entity, only entities will get classified and vice-versa. It is used for classification in /classify and /loader/doc APIs.
• anonymizeSnippets: Flag to anonymize snippets in report. Possible values are 'True' and 'False'. When its value is 'True', snippets in reports will be shown as anonymized and vice versa.

Storage

This is beta feature introduced in 0.1.18.

• type: Specifies storage type to store states of the GenAI applications. Possible values are file or db. Default value is file. By default, SQLite database is used when we set it as db.
• type as file is deprecated, use type as db. file would not be supported from 0.1.19 release.

Default Configuration

daemon:
  port: 8000
  host: localhost
logging:
  level: info
reports:
  format: pdf
  renderer: xhtml2pdf
  outputDir: ~/.pebblo
classifier:
  anonymizeSnippets: False
storage:
  type: file

Note: Users have the option to maintain any section or even a single field within a section. For instance, the config file might appear as follows:

logging:
  level: info

This flexibility empowers users to tailor configurations to their specific needs while retaining default values for other sections or fields.
